But May said another vote would be a "gross betrayal" of British democracy and trust. Here's her quote in full, from The Sunday Telegraph:

"In the summer of 2016, millions came out to have their say. In many cases, for the first time in decades they trusted that their vote would count; that after years of feeling ignored by politics, their voices would be heard.

"To ask the question all over again would be a gross betrayal of our democracy — and a betrayal of trust."

But Sunday's intervention is the most strident she has been in her language. Also in the Telegraph, May added that she will not accept any compromises to her Chequers Brexit plan "that are not in our national interest."

The prime minister is "confident" that the government can strike "a good deal," but said Britain would "be ready if we need to be" in the event of not securing a deal from the EU, and that the country would "go on to thrive."
